saidgroo'ves forming means `whereby either sash` may be raised orlowered as desired.

Af further object to provide the "frame with metallic fstrips angularlyshapedfin cross section, oneV flange of whichis received" ingroove'sinthe outer sideso the 'sash for forming a dust and weatherproof` joint.

A further object is to providethelower ends of the sash withiiXed-pinsextendinggto the channel' 'for forming pivotaf'lpoints for thesash and the upper end of the sash with retractable pins, which whenretracted allow the sash to swing inwardly to horizontal positions whenit is desired to repair or ckian the outer sides of the sash.

Vith the above and other objects in view the invention resides in thecombination and arrangement of parts as hereinafter set forth, shown inthe drawing, described and claimed, it being understood that changes inthe precise embodiment of the invention may be made within the scope ofwhat 1s claimed without departing fromthe spirit of the invention.

In the drawing Figure 1 is a perspective view of the window Jframe.

Figure 2 is a vertical transverse sectional view through the windowframe and sash.

Figure 3 is a horizontal sectional view taken on line 3--3 of Figure 1.

Figure 4 is a sectional view taken on line f* 4-4 of Figure 1.

Figure 5' is a vertical transverse `sectional Figure 6 is@ alperspective view' ofone of the .up11er pivot bolts of the sash; s FigureT ieg aV perspective view of one` of thezstiirlmbO-lts: l -V Referringtoi the 1 drawing; the numeral 1%, designates the-windowgfiane, thesides 2-ofwhich areprovided'withshoulders Sand 4f, and against theshoulders 3 weajtlrcrs trips are" disposed, which weatherstfrips arefright angular-ly shaped` in' i cross section, `andhave'jV one' oftheirflanges-f disposed in channels 6- in thejouter-faces'ofthewindowsash 7 for] formingl a dust:A proof connection. It y 'will that the sash7; may be easilyA placed inthe' `7() he notedgthat-the' shoulders 3f and4 arein staggeredrelation thereioreit'willbe seen irame; 1A orAremovedtherefrom from the in- `ner` side rofthe frame, thereby allowingthe' sash -to-be easily removed` for reputtying or cleaningEpurposes,i`The shoulders 3 and-4' extendacross the-upperend of the' frame as* wellas the lstripsf, thereforeit will Ahe seerr that i al dust and weatherproof connection is* formed alongthe verticalisides of the sash and alsoalong thefupper endf` of the upper sash. The-scrcen'S isoi-inedpreferably in two, sections asclea-rly shown in Figure '2 andi-frestagainst the shoulders 45 of the frame,` therefore it will beiseenfthat the screen may he easily removed from" theV frame inwardlytherethrough', thereby obviating the difficulty of placing screens inposition, at present experienced, especially with full length screens.The adjacent ends of the sash 7 overlap clearly shown in Figure 2, andare provided with angular weather strippingl 9, similar in constructionand operation as the strip 5. l

The lower ends of the sash 7 have secured thereto plates 10, whichplates are provided withV lugs 11, which extend into theverticallydisposed grooves 12 and lguide the sash in its upwardmovement, and at the same time upon inward pivotal movement of the sashform pivotal points thereifor. The grooves 12 are disposed in the sidesof the frame 1 in a position where they are substantially concealed bysash when in normal position as shown in Figure Q. The upper ends oiEthe grooves 12 terminate in upwardly andinwardly inclined grooves 13,which in turn terminate in horizontally disposed grooves 14, in whichgrooves the retractable lit eli)

lugs 15, carried by the plates 16,` at the upper ends of the sash, aredisposed, that is of the upper sash. Vhen it is desired to lower theupper sash 7 after the lower sash has been moved inwardly, .the uppersash is pulled inwardly at its upper end, which will n'iove theretractable lug 15 to a position where they will be received in theinclined grooves 13, and the sash out of engagement with the upperportion of the weather `strip 5, after which the sash can be moveddownwardly, guided by the lugs 15 and the lugs llin the groove 12. Framel is provided with grooves 16 inwardly spaced from the grooves 1Q and inparallel relation therewithM The lower ends of the grooves 16 inclinedownwardly and outwardly at 17 and are connected to the lower end of thegrooves 1Q. They are also connected to the grooves 12 adjacent the upperend of the lower sash by ineans of horizontally disposed grooves 1S,therefore it will be seen that the lower sash niay be pulled inwardly atits upper end for forcing' the retractable lugs l5 through the grooves18 into the Grooves 1G and then the lower sash can be raised, and thelugs 15 and 11 thereof forced upwardly into the grooves 16. When it isdesired to swing the sash inwardly for repairing or cleaning the outersides thereof, it will only be necessary for the operator to retract theretractable lugs 15 at the upper ends of the sash, which will allow saidsash to swing inwardly on the lugs 11 as pivotal points, and the sashniay be placed in a horizontal point or at any other angle. The oppositesides of the sash 7 are preferably provided with storin bolts 19 whichadditionally hold the sash against movement and in position. However to:turther hold the sash and lock the saine together a conventional forniof pivoted ring controlled latching device is provided on the lower sashwhich cooperates with the upper sash as clearly shown in Figure 5.

From the above it will be seen that a window frame and sash is providedwhich is siinplein construction, positive in its operation andconstructed ina manner whereby the sash will not only form a dust proofwindow, but one wherein all of the sash can be easily and quicklyrenioved from the inside of the frame, or the sash placed in positionwhere the outer sides thereof niay be easily repaired or cleaned.

The invention having been set forth what is claimed as new and useful isA sash mounting for window frames coinprising vertically disposedparallel grooves in the inner faces of a window frame, guide lugscarried by the sash adjacent their upper and lower ends, the upper guidelugs being retractable, the lower ends of said grooves being connectedtogether by means of downwardly and outwardly inclining grooves,connecting horizontal grooves between the vertically disposed groovesad,- jacent the upper guide lugs of the lower sash and inwardly,upwardly and outwardly inclined grooves carried by the upper ends ot'the outer vertical grooves adjacent the upperguide lugs, said lupperguide lugs being retractable vertically disposed and inwardly extendingstrips carried by the window trarne and disposed in channels in theouter iaces 'of the sash, horizontally disposed inwardly extendingflanges carried by the upper side of the frame and the lower end of theupper sash and disposed in horizontally disposed channels in theadjacentsash ends, said flanges forming weather strips and locking meansfor the sash.

In testimony whereof I hereunto aiix niy s i gnature. i
